Answer: weigh is m = n × M = 2.87 mol × 58.44 g/mol
Explanation: mass = amount of substance × molar mass
M((NaCl) = 22.99 +35.45
Answer:
Molecules move from areas of high concentration to areas of low concentration.
Moles = Molarity x Volume
Moles = 2.0 x 0.50
= 1.0 mole
hope this helps!
Answer:
930 g
Explanation:
D = m/V Multiply both sides by V
m = VD
<em>Data:
</em>
V = 372 cm³
D = 2.70 g/cm³
<em>Calculation:
</em>
m = 372 × 2.50
m = 930 g
The mass of Al is 930 g.
