How many atoms are in 125 grams of Calcium?
To find the number of atoms in 125 grams of calcium, you first need to convert the mass to moles using the molar mass of calcium. Then, you can use Avogadro's number (6.022 x 10^23) to find the number of atoms in one mole of calcium. Finally, multiply the number of moles by Avogadro's number to find the total number of atoms in 125 grams of calcium.
What is the mass of 0.05 moles of oxygen?
One mole is 6.02 × 1023 of anything. One mole of atoms is 6.02 × 1023 atoms, one mole of rice is 6.02 × 1023 grains, one mole of shoes is 6.02 × 1023 shoes.So you multiply 5 with 6.02 × 1023 to get 3.01 × 1024
How much carbon is in 3point 49 times 10e22 atoms of carbon answer in units of moles?
To calculate the amount of carbon in moles, we first need to find the molar mass of carbon, which is approximately 12 g/mol. Next, we convert the number of atoms to moles by dividing by Avogadro's number (6.022 x 10^23). The answer is approximately 2.05 moles of carbon.
A vat of hydrogen peroxide H2O2 contains 455 grams of oxygen atoms how many molecules of H2O2 are in the vat?
To find the number of molecules of H2O2 in the vat, we first need to calculate the number of moles of oxygen atoms. Using the molar mass of oxygen (16 g/mol), we find that 455 grams of oxygen is equivalent to 28.44 moles. Since each molecule of H2O2 contains 2 oxygen atoms, the number of H2O2 molecules in the vat would be 2 times Avogadro's number (6.022 x 10^23) times the number of moles of oxygen atoms, or approximately 3.43 x 10^24 molecules.
How many atoms are there in 5.10 grams of sulfur?
To find the number of atoms in 5.10 grams of sulfur, you first need to determine the molar mass of sulfur, which is 32.06 g/mol. Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to calculate the number of atoms in 5.10 grams of sulfur.
What does 14.17 grams times 15.00 equals?
14.17 x 15.00 = 212.55 Therefore the answer is 212.55 grams
40 500mg tablets times equals what in grams?
20 g
How many grams of oxygen are in 477 grams of water?
There are 424 grams of oxygen in 477 grams of water. 8 times 53 equals 424.
What is the mass of 9 atom(s) of copper in grams?
The atomic mass of copper is approximately 63.55 g/mol. Therefore, the mass of 9 atoms of copper would be 9 times the atomic mass, which is 9 * 63.55 g/mol. This equals 571.95 grams.
How many atoms are in 25.1 grams in sulfur?
To find the number of atoms in 25.1 grams of sulfur, you first need to calculate the number of moles using the molar mass of sulfur (32.06 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. So, number of atoms in 25.1 grams of sulfur would be: ( \dfrac{25.1 , \text{g}}{32.06 , \text{g/mol}} \times 6.022 \times 10^{23} , \text{atoms/mol})
What is greater 2500 grams or 2.5 kg?

What is oz in grams?
1 ounce = 28.35 grams.
How many grams would 25 penny weights be in gold?
1 dwt is 1 penny weight. 1 dwt (penny weight) equals 1.55517384 grams. 1 troy ounce of gold weighs 31 grams. 25 dwt's times 1.55517384 grams, equals 38.879345 grams of gold.
.5 kilogram equal how many grams?
1 kilogram is equal to 1,000 grams, therefore, 5 grams is .005 kilograms.
HOW MANY PEANUTS IN 30GR?
There are about 10-12 peanuts per 10 grams. If 10 grams times 3 equals 30 grams, then 10 to 12 peanuts multiplied by 3 equals 30 to 36 peanuts. Side note: 30 grams is equivalent to 1/4 cup.
How many times would 850 grams to a pound?
