Convert the given masses to moles.
• (55.0 g Na) (1/22.989 mol/g) ≈ 2.39 mol Na
• (67.2 g Cl₂) (1/70.9 mol/g) ≈ 0.948 mol Cl₂
The reaction consumes a ratio of 2 mol Na to 1 mol Cl₂, which means 0.948 mol Cl₂ reacts with 2 × 0.948 ≈ 1.90 mol Na, leaving an excess of about 0.494 mol Na.
The amount of NaCl produced is the same as the amount of Na consumed, so we end up with about 1.90 mol NaCl, which has a mass of about
(1.90 mol NaCl) (58.44 g/mol) ≈ 111 g NaCl
Any process to have heat transfer from a cooler to a hotter object as its sole result.
The number of clocks that are not defective is an illustration of proportions
Of the 10000 clocks, 9250 are probably not defective
<h3>How to determine the number of clocks that are not defective?</h3>
From the complete question, we have the following parameter:
15 out of 200 clocks are defective
The above means that the number of clocks that are not defective is:
Not defective = 200 - 15
Not defective = 185
Express as percentage
Not defective = 185/200
Not defective = 92.5%
In 10,000 the number of clocks that are not defective would be:
Not defective = 92.5% * 10000
Not defective = 9250
Hence, 9250 of the 10000 clocks are probably not defective
