How many atoms are in 30 moles of iron?
A mole is 6.022×1023 of anything, including atoms. So to determine the number of atoms are in 30 moles of iron, you multiply the number of moles times 6.022×1023. 30mol Fe x 6.022×1023 atoms Fe/1mol Fe = 1.8066×1025atoms Fe When corrected for significant figures, the answer is 2×1025atoms Fe. Note: the number following the 10 in the large numbers is the exponent on the 10 and should be written as superscripts, but that is not supported at the moment.
How many carbon dioxide molecules are needed to produce 3 molecules of glucose?
Each glucose molecule contains 6 carbon atoms. Thus we need 18 molecules of CO2 to make 3 molecules of glucose.
How many moles of Fe are present in 30 grams in rust?
This amount may be different because rust is not a clearly definite compound.
Calculate the amount of CO2 in the moles that forms if 10 mol of c3h4 react according to the following balanced equation c3h4 4o2-3co2 2h2o?
From the balanced equation, we can see that 3 moles of CO2 are formed for every 1 mole of C3H4 that reacts. Therefore, if 10 moles of C3H4 react, 30 moles of CO2 would be formed (10 moles C3H4 x 3 moles CO2/1 mole C3H4).
How many atoms in iron?
26 protons 26 electrons and 30 neutrons
How many moles of silver atoms are in 1.8 x 10 25 atoms of silver?
To calculate the number of moles, you divide the number of atoms by Avogadro's number (6.022 x 10^23). So for 1.8 x 10^25 atoms of silver, the number of moles would be 30 moles.
How many atoms of al are present in 30 grams?
To find the number of aluminum atoms in 30 grams, you first need to determine the number of moles of aluminum using its molar mass (26.98 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms.
How many moles of oxygen gas in 30 times 10 to the power of 23 atoms of oxygen?
very roughly 5 moles...avagadros number = 6.022 x 1023 just devide 30 by this number

How many hydrogen atoms are in 8e-15 moles of C12 H30 O5 please include method of solving the problem?
First multiply 8e-15 by 6.022e23 to get the number of atoms and multiply that by 30 ( the number of hydrogen atoms)
3 moles equals how many molecules?
One mole contains 6.022 x 10^23 molecules. Therefore, 3 moles would equal (3 x 6.022 x 10^23) = 1.8066 x 10^24 molecules.
How many moles of carbon dioxide are produced when 10.0 moles of propane are burned in excess oxygen on gas grill?
30 moles
How many grams of helium are contained in a 2.0 L balloon at 30 degrees Celsius and at 735 mm Hg?
To find the number of grams of helium in the balloon, you need to use the ideal gas law equation. First, convert the temperature to Kelvin by adding 273 (303 K). Then, convert the pressure to atm (0.966 atm). Now, use the ideal gas law formula: PV = nRT, where P is pressure, V is volume, n is moles, R is the ideal gas constant, and T is temperature in Kelvin. Solve for n (moles), which equals 0.08 moles of helium. Finally, calculate the mass using the molar mass of helium (4 g/mol) multiplied by the number of moles (0.08 mol), which equals 0.32 grams of helium.
How many atoms are present in 4.0 mole of sodium?
There are approximately 2.41 x 10^24 atoms in 4.0 moles of sodium. This calculation is done by multiplying Avogadro's number (6.022 x 10^23) by the number of moles.
If 10 moles of A3 are reacted with excess B2 how many moles of AB will be produced 2A3 plus 3B2 6AB?
From the balanced equation, 2 moles of A3 react with 3 moles of B2 to produce 6 moles of AB. Therefore, if 10 moles of A3 are reacted, the ratio of moles of AB produced would be (10 moles A3 / 2 moles A3) * 6 moles AB = 30 moles AB.
2A3 plus 3B2 6AB If 10 moles of A3 are reacted with excess B2 how many moles of AB will be produced?
For every 2 moles of A3, 3 moles of B2 react to form 6 moles of AB. Since we have 10 moles of A3, we need to double the moles of B2 reacting, which would be 15 moles of B2 to fully react with the 10 moles of A3. This would produce 30 moles of AB.
How many atoms are in 6PCl5?
6PCl5 contains 6 phosphorus atoms and 30 chlorine atoms, totaling 36 atoms in total.
