Calculate the density of helium if a balloon with a capacity of 5.00 L holds 0.890 g.
liubo4ka [24]

Answer:

Explanation:

Density is m/V. Also, 1 liter = 1000 cm^3. So, we get 0.890/(5*1000) = 1.78*10^{-4} g/cm^3. You can convert this to kg/m^3 as well by multiplying it by 10. Depends which one you want.

A solution is made by dissolving 10.7 g of magnesium sulfate, MgSO4, in enough water to make exactly 100 mL of solution. Calcula
adell [148]

Answer:

[MgSO₄] = 890 mM/L

Explanation:

In order to determine molarity we need to determine the moles of solute that are in 1L of solution.

Solute: MgSO₄ (10.7 g)

Solvent: water

Solution: 100 mL as volume. (100 mL . 1L / 1000mL) = 0.1L

We convert the solute's mass  to moles → 10.7 g / 120.36 g/mol = 0.089 moles

Molarity (mol/L) → 0.089 mol/0.1L = 0.89 M

In order to calculate M to mM/L, we make this conversion:

0.89 mol . 1000 mmoles/ 1 mol = 890 mmoles
