Since we already have the balanced equation, we know that the ratio between is respectively.
So then we can set up a proportion to find the number of moles produced when 2.90 moles of Na react completely:
Then we cross multiply and solve for x:
Therefore, we know that when 2.90 moles of Na react completely, there are 1.45 moles of that are produced.

Explanation:
199.5 g of sucrose is needed to make 665 ml of 30 % weight by volume percent solution.
<h3>What is percent solution?</h3>
Percent solution is defined as a convenient way to record concentration of solution.It is a expression which relates solute to solvent as,mass of solute/mass of solution ×100.There are two types of percentage solutions percent weight by volume and percent volume by volume .Advantages of using percent solutions is that molecular weight of compound is not required.
This example is percent weight by volume where mass of solute is calculated as,%(w/v)= mass of solute/mass of solution×100
substitution of values gives,30×665/100=199.5 g
Thus ,199.5 g of sucrose is required to make 665 ml of 30 % sucrose solution.
