Answer:
1.7 M
Explanation:
Concentration is the number of moles of solute dissolved in 1 L of solution
Concentration = number of moles of solute / volume of solution
Number of moles of solute needs to be calculated first
Mass of methanol - 12.5 g
Molar mass of methanol - 32 g/mol
Number of methanol moles - 12.5 g / 32 g/mol = 0.39 mol
Therefore concentration is = 0.39 mol / 0.230 L = 1.7 mol/L
Concentration is 1.7 M

for ex the force of gravity if there was no equal force there would be a technical gravity
Answer:
The answer to your question is: Volume = 1.074 x 10⁻⁶ m³
Explanation:
Data
Salt crystal measures 5.44 x 10⁻² m ; 2.5 x 10⁻³ m; 7.9 x 10⁻³ m
From the information I suppose it is a cube, then,
Volume of a cube = length x width x height
Volume = 5.44 x 10⁻² m x 2.5 x 10⁻³ m x 7.9 x 10⁻³ m
Volume = 0.000001074 m³
Volume = 1.074 x 10⁻⁶ m³
