What is the mass of an object with a density of 3.4 g/mL and a volume of 500.0 mL

umka2103 [35]

Formula:
$mass=density *volume$

Given:
Density=3.4
Volume=500.0

Plug them into the formula:
$mass=3.4 *500.0=1700$

Final answer: 1700g

Calculate the molarity of a solution that contains 0.250 moles of kf in 0.500 l of water

MakcuM [25]

Molarity can be defined as the number of moles of solute in 1 L of solution.

M = n/V

Where M is the molarity of the solution (M or mol/L), n is the moles of the solute (mol) and V is the volume of the solution (L).

Here, solute is KF.

n = <span>0.250 mol
</span>V = 0.500 L
M = ?

By applying the formula,
M = 0.250 mol / 0.500 L
M = 0.500 mol/L

Hence, the molarity of KF solution is 0.500 mol/L.
