Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A stoichiometric computation in which the mass of products is determined from the given mass of reactants
A
atoms to atoms calculation
B
molecules to molecules calculation
C
Avogadro’s # to Avogadro’s # calculation
D
mass to mass calculation
Explanation: 

Detailed explanation-1: -Mass-mass calculations involve converting the mass of a reactant to moles of reactant, then using mole ratios to determine moles of product which can then be converted to mass of product.

Detailed explanation-2: -1) Make sure the chemical equation is balanced! 2) Determine which reactant is the limiting reagent . 3) Use the limiting reactant to convert from moles of reactants to moles of products. 4) Use the molar mass to convert the moles of product to mass.

Detailed explanation-3: -Stoichiometry uses the proportional nature of chemical equations to determine the amount of reactant needed to produce a given amount of product or predict the amount that will be produced from a given amount of reactant.

Detailed explanation-4: -Balance the equation. Convert units of a given substance to moles. Using the mole ratio, calculate the moles of substance yielded by the reaction. Convert moles of wanted substance to desired units.
