Question

How to find the final mass of a combined sample in chemistry?

(a) Apply the Ideal Gas Law
(b) Use the conservation of mass
(c) Calculate using the atomic mass
(d) Measure using a balance

Answer 1

To find the final mass of a combined sample in chemistry, you need to balance the chemical equation, convert from volume to mass, determine the limiting reactant, and convert from moles of product to mass of product.

Step-by-step explanation:

B. Use the given densities to convert from volume to mass. Then use each molar mass to convert from mass to moles.

C. Using mole ratios, determine which substance is the limiting reactant. After identifying the limiting reactant, use mole ratios based on the number of moles of limiting reactant to determine the number of moles of product.

D. Convert from moles of product to mass of product.

So, to find the final mass of a combined sample in chemistry, you need to balance the chemical equation, convert from volume to mass, determine the limiting reactant, and convert from moles of product to mass of product.
