Why do you need 40 grams of calcium and 32 grams of sulfur to make 72 grams of calcium sulfide?
From the periodic table, calcium has a molar mass of 40.078g/mol and sulfur has a molar mass of 32.065g/mol. The formula for compound formed from calcium and sulfur, calcium sulfide is CaS. The molar mass of CaS is 72.143. So, if you round the numbers, 40g of Ca + 32g of S will produce 72g of CaS.
If all of the 120g of glucose are converted within muscle cells to energy ATP how many grams of H20 will be produced how many grams of C02 will be produced?
When 120g of glucose is converted to ATP in muscle cells, it produces 72g of water and 264g of carbon dioxide. This process involves the breakdown of glucose through cellular respiration, where glucose is oxidized to produce energy (ATP), water, and carbon dioxide.
What is the total mass of water formed when 8 grams of hydrogen reacts completely with 64 grams of ovygen?
The balanced chemical equation for the reaction of hydrogen and oxygen to form water is 2H2 + O2 -> 2H2O. Based on the equation, for every 2 grams of hydrogen, 64 grams of oxygen are needed to form 36 grams of water. Thus, if 8 grams of hydrogen react completely with 64 grams of oxygen, the total mass of water formed would be 36 grams.
The mass of the rock is 12 grams what is the density of the rock?
density= mass/ volume D= 36/12 =3g/cm3
How many mg are in 72g?
72,000 mg
How do you calculate the number of moles from the mass?
This is a generic answer with an example of how to solve this kind of problem. You can use the technique given here to find the answer to your particular problem. First you need to find the molecular weight of the compound. Once you've done that, then you simply divide the mass of the compound (in grams) by the molecular weight of the compound (in amu). The result is the number of moles. For example: Water (H2O) has a molecular weight of 2 * 1.0 (for the two hydrogens, 1 amu each) + 1 * 16.0 (for the oxygen, 16 amu) or 18.0 amu. So if I have 27.0 grams of water, then I have 27.0 / 18.0 = 1.5 moles of water.
What is 72g in pounds?
Far less than 1 pound. 72 grams is 0.15 pounds.

How do you convert 72g to mg?
Multiply by 1000 =72,000 mg
How many moles of water are on 72.08g of H2O?
To determine the number of moles of water in 72.08g of H2O, we first need to calculate the molar mass of water (H2O). The molar mass of water is approximately 18.015 g/mol (2 hydrogen atoms with a molar mass of 1.008 g/mol each, and 1 oxygen atom with a molar mass of 16.00 g/mol). Next, we use the formula: moles = mass / molar mass. Plugging in the values, we get moles = 72.08g / 18.015 g/mol ≈ 4 moles of water. Therefore, there are approximately 4 moles of water in 72.08g of H2O.
What is the molar mass of C6Cl6?
The molar mass of C6Cl6 (carbon tetrachloride) is approximately 253.73 g/mol. This can be calculated by adding the atomic masses of carbon (12.01 g/mol) and chlorine (35.45 g/mol) for each atom in the compound.
How many grams of pentane are needed to produce 72g of water?
Start with a balanced equation: C5H12 + 8O2 --> 5CO2 + 6H2OFind the number of moles of water in 72 g: FW of H2O is 18 g/mol so 72g/18g/mol is 4 molRecall from the balanced equation the number of moles of water produced for each mole of Pentane: 6 waters for each pentaneYou produce 4 moles of water so the ratio from the balanced equation says you will need 4/6 mole of pentaneFind the FW of the pentane: It (coincidentally) comes 72 grams/molSo, 0.67 mol of pentane times 72 g/mol will give the final answer of 48.24 grams
