How many grams are in 3.5 moles?
The mass of 3.5 moles of Ca is 140 g to two significant figures.
How many grams per mole are in H2O?
18.02 grams
The average mass of one mole of H2O is 18.02 grams.
How many grams of water can be produced from the reaction of 45 g of O2?
Use the following to answer questions 5-8. How many moles of water can be produced from the reaction of 45 g of O2? 45 g O2 X 1 mole O2 X 4 moles H2O = 1.125 moles H2O 32 g O2 5 moles O2 8.
What is the mass of 5 moles of h2o?
Since one mole of water is made of two moles of Hydrogen (1.01 g/mol) and one mole of Oxygen (15.99 g/mol) its mass would be 18.01 g. Five moles of water whould have a mass of 90.05 g.
How many grams of H2O are produced if 2.02 g of H2 react with excess O2?
The answer is 18 grams.
How many grams of water can be produced by the reaction of 8 grams of oxygen and 8 grams of hydrogen?
So 8 g of oxygen will react with 1 g of hydrogen to produce 9 g of water.
How many moles is 25 grams of water?
1.38 moles
Hence, 1.38 moles (mol) are present in 25 grams of water.
How many moles are required to completely react with NH3?

How many moles of O2 react with 2moles of Cao?
Given the chemical equation: 2 Ca + O2 → 2 CaO,if 2 moles of CaO are formed in this reaction, then 2 moles of O2 must have reacted. Before determining conversion factors, it is necessary to make sure the equation is properly balanced.
How many moles of initial feed are there from C5H12 and O2?
If the reactants C5H12 & O2 are having 2 moles an 8 moles of initial feed respectively. 1. Which is the excess reactant in the reaction? Balance the following chemical equation.
How many moles of MgO will form when magnesium reacts with O2?
The balanced chemical equation is: O2 + 2 Mg → 2 MgOIf 4 moles of magnesium totally reacted with more than enough O2, how many moles of MgO would be expected to form? Given the chemical equation: 2 Ca + O2 → 2 CaO,if 2 moles of CaO are formed in this reaction, then 2 moles of O2 must have reacted.
