<h2>
Answer: 8.93 g/cm³</h2>
<h3>
Explanation:</h3>
Density = mass ÷ volume
= 217.0 g ÷ 24.3 cm³
= 8.93 g/cm³
<h3>∴ the unknown sample of mass 217.0 grams and volume of 24.3 cm³ has a density of 8.93 g/cm³.
</h3>
Answer:
Explanation:
The expression for the root mean square speed is:
R is Gas constant having value = 8.314 J / K mol
M is the molar mass of gas
Molar mass of water vapor = 18.0 g/mol = 0.018 kg/mol
Temperature = ?
m/s

<h3><u>Answer</u>;</h3>
Actual yield = 46.44 g
<h3><u>Explanation;</u></h3>
1 mole of water = 18 g/mol
Therefore;
The experimental yield = 2.58 moles
equivalent to ; 2.58 × 18 = 46.44 g
The theoretical value is 47 g
Percentage yield = 46.44/47 × 100%
= 98.8%
The questions asks for actual yield = 46.44 g
