Answer is "0.05 mol".
<em>Explanation;</em>
We can do calculation by using a simple formula as
n = m/M
Where, n is the number of moles of the substance (mol), m is the mass of the substance (g) and M is the molar mass of the substance (g/mol).
Here,
n = ?
m = 2.80 g
M = 56.08 g/mol
By substitution,
n = 2.80 g /56.08 g/mol
n = 0.0499 mol ≈ 0.05 mol
Yes a compound a thing that is composed of two or more separate elements; a mixture.
Answer:
1109 g H₂O
Explanation:
2.2 pounds can be converted to grams using a conversion ratio:
(2.2lb)(453.592g/lb) = 997.9024 g C₅₇H₁₁₀O₆
The mass in grams is converted to moles using the molecular weight of tristearin (891.48 g/mol)
(997.9024 g)(mol/891.48g) = 1.119...mol C₅₇H₁₁₀O₆
The moles of C₅₇H₁₁₀O₆ can be related to the moles of water through the molar ratio:
(1.119mol C₅₇H₁₁₀O₆)(110 H₂O/2 C₅₇H₁₁₀O₆) = 61.545 mol H₂O
The mass of water is then calculated using the molecular weight (18.02 g/mol):
(61.545 mol)(18.02 g/mol) = 1109 g H₂O
