Answer:

The answer to your question is 42.9 g of Ca

Explanation:

Data

mass of Ca = ?

mass of N₂ = 10 g

Balanced  chemical reaction

                 3Ca  +  N₂  ⇒   Ca₃N₂

Process

1.- Calculate the molar mass of the reactants.

Ca = 3(40) = 120 g

N₂ = 2(14) = 28 g

2.- Calculate the mass of Calcium using proportions and the molar mass of the reactants.

                    120 g of Ca ---------------- 28 g of N₂

                       x               ---------------- 10 g of N₂

                               x = (10 x 120) / 28

                               x = 1200 / 28

                               x = 42.9 g of Ca

The protocol for a given lab experiment specifies that you should prepare 100 mL of a 0.10 M (mol/L) aqueous solution of NaNO3.
Nat2105 [25]

Answer:

It should be transferred to a Beaker to finish preparing the solution

Explanation:

NaNO₃ is sodium Nitrate. It is a salt that is soluble in water hence it's aqueous solution can be prepared by dissolving it in water.

A beaker is a laboratory glassware that is used for various functions; one of which includes the preparation of reagents or aqueous solutions of a compound. In the example narrated in the question, the measured NaNO₃ solid can be transferred to a 100 mL or 200 mL beaker and then added to it is the desired volume of water to make the solution 100 mL. This solution can then be stirred with a "glass rod"
