Practice ICSE Class 10 Mole Concept and Stoichiometry in the app →Avogadro's number is:One mole of any gas at STP occupies:The molar mass of CO2 is approximately:Number of molecules in 0.5 mole of N2 is:How many moles are in 36 g of water?Volume of 2 moles of O2 at STP is:Number of atoms in one mole of helium is:Number of moles in 88 g of CO2 (molar mass 44) is:Empirical formula of glucose (C6H12O6) is:Molar mass of NaCl is approximately:How many grams of CO2 are produced when 12 g of carbon burns completely?Density of methane gas (CH4) at STP:How many moles of HCl are in 100 mL of 0.5 M HCl?Total atoms in one mole of H2O are:From the equation 2H2 + O2 -> 2H2O, the number of moles of H2O formed from 2 moles of H2 is:What is the molar mass of (NH4)2SO4?If 4 moles of A react with 6 moles of B as 2A + 3B -> 2C, which reactant is in excess?Mass of 1 atom of carbon (atomic mass 12) is approximately:Which contains the LARGEST number of atoms?The volume of 7 g of nitrogen (N2, molar mass 28) at STP is:How many oxygen atoms are present in 49 g of H2SO4 (molar mass 98)?What is the percentage of hydrogen in water (H2O)?Two gases at the same temperature and pressure occupy equal volumes. What does this mean?How many moles of water are in 1 L at 4 C? (Density of water = 1 g per mL, molar mass H2O = 18)If 2 g of hydrogen reacts with 16 g of oxygen, what is the limiting reagent?
