Does 23 g of sodium and 238 g of uranium have equal number of atoms in them?
No, the number of atoms in a substance is determined by Avogadro's number (6.022 x 10^23 atoms/mol). To calculate the number of atoms, you need to convert the mass of each element to moles first using their respective molar masses, which are 22.99 g/mol for sodium and 238.03 g/mol for uranium.
Mass of uranium atom?
The mass of a uranium atom is approximately 238 atomic mass units. It is one of the heaviest naturally occurring elements.
What is the equivalent measurement of 238 grams on a measurement cup?
238 grams is equivalent to approximately 1 cup when measuring flour, but it can vary slightly depending on the ingredient being measured. It is always best to use a kitchen scale for precise measurements, especially when baking.
What do the '238' in uranium-238 and the '14' in carbon-14 mean?
The numbers in uranium-238 and carbon-14 refer to the atomic mass of the isotopes. The number '238' indicates that uranium-238 has a total of 238 protons and neutrons in its nucleus, while the number '14' indicates that carbon-14 has a total of 14 protons and neutrons.
What number is written after the isotope when writing the name?
The number written after the isotope in the name indicates the mass number of the isotope. It represents the total number of protons and neutrons in the nucleus of the atom.
How many gram are in 238 moles of arsenic?
To convert moles to grams, you need to know the molar mass of arsenic. Arsenic has a molar mass of approximately 74.92 g/mol. Therefore, to find the grams in 238 moles of arsenic, you would multiply the number of moles by the molar mass: 238 moles x 74.92 g/mol = 17,827.76 grams of arsenic.
How do you solve for how many grams are in 2.38 moles of calcium carbonate?
To convert moles to grams, you need to use the molar mass of calcium carbonate (CaCO3). The molar mass of CaCO3 is approximately 100.1 g/mol. To calculate the grams in 2.38 moles of CaCO3, you would multiply the number of moles (2.38) by the molar mass (100.1 g/mol), which gives you approximately 238 grams.
How many grams in 238 moles of arsenic?
To calculate the mass of 238 moles of arsenic, you would first need to determine the molar mass of arsenic, which is approximately 74.92 g/mol. Multiplying the molar mass by the number of moles gives you the mass: 238 moles * 74.92 g/mol = 17,828.96 grams of arsenic.
What is the molar mass of uranium -238?
238 grams/mole The isotopic number is the approximate mass for any element. Such as if I say Carbon 14, the approximate mass is 14 grams/mole. If you are asking what is the mass of one atom of Uranium 238: Then you take the isotopic mass 238 grams/mole and divide by Avogadro's Number 6.022X10^23 atoms/mole this gives you units of grams/atom.
A ball has a mass of 238 grams a box holds 9 balls the total mass of the balls and the box is 2437 grams Estimate the mass of the box?
The mass is 295 grams. This is multiplication and subtraction. 9 x 238 = 2142 grams for the balls Total - ball mass = box mass 2437 - 2142 = 295 grams
What are the molar mass of uranium 238?
Pure Uranium-238 has an Atomic Mass of 238.1252 amu. Thus one mole of it weighs 238.1252 grams.
What is the mass in gram of 0.500 mole of uranium?
The molar mass of uranium is approximately 238 grams per mole. Therefore, 0.500 mole of uranium would have a mass of 0.500 x 238 = 119 grams.
How many moles of NaCl is 43.83grams of NaCl?
1 mole of NaCl: Na = 1 * 22.99 g = 22.99 g Cl = 1* 35.45 g = 35.45 g Total = 58.44 g 238 g NaCl * (1 mol NaCl/58.44 g NaCl) = 4.07 mol NaCl There are approximately 4.1 moles in 238 grams of sodium chloride.
How many ml is 230 grams?
The number of milliliters to have a mass of 238 g depends upon the mass density of the substance. For pure water at 4.0 C : ----------------------------------- d = 1.000 g per mL d = m / V ..... [ By Definition of mass density ] V = m / d = ( 238 g ) / ( 1.000 g /mL ) = 238 mL <------- For methanol at 10 C : --------------------------- d = 0.801 g / mL V = m / d = ( 238 g ) / ( 0.801 g / mL ) = 297 mL <-----------
How many ounces is 238 grams?
To convert grams to ounces, you can use the conversion factor that 1 ounce is approximately equal to 28.35 grams. Therefore, 238 grams is approximately equal to 8.4 ounces (238 grams / 28.35 grams per ounce).
Does 23 g of sodium and 238 g of uranium have equal number of atoms in them?
