Answer:
<h3>H2O (water)</h3><h3>N2 (nitrogen)</h3><h3>O3 (ozone)</h3><h3>CaO (calcium oxide)</h3><h3>
Explanation:</h3>
<u>H</u><u>OPE </u><u>IT</u><u> HELPS</u>
With a good mask-to-face seal and an oxygen flow rate of 15 L/min, the nonrebreathing mask is capable of delivering up to 90% inspired oxygen.
<h3>What is fraction of inspired oxygen?</h3>
FiO2 is the fraction of inspired oxygen which is explained as the concentration of oxygen inhaled by a person.
<h3>Non breather mask:</h3>
It delivers a high concentration of oxygen. Hence the liter flow will be 8-15L/min with the percentage of oxygen between 60-90%.
The liter flow of nonbreathing mask must not be less than 8L/min.
From the above information we can conclude that the fraction of inspired oxygen for a nonbreathing mask is 90%

I can't give an exact answer if you do not provide any unit of concentration. The most common unit of concentration is molarity, which is the number of moles of solute over the number of liters solution. Say for example, the concentration of the solution is 0.1 M. To find the equivalent mass percentage, the solution is as follows:
The molar mass of Sr(NO₃)₂ is <span>211.63 g/mol.
(0.1 mol </span>Sr(NO₃)₂/ L solution)(211.63 g/mol)(1 L solution/ 1 kg solution)(1 kg/1000 g solution) * 100 = <em>2.12% Sr(NO₃)₂ solution</em>
