The 2 parts or components that make up a solution would be the solute and the solvent.
The density of He is 1.79 x 10⁻⁴ g/mL
In other words in 1 mL there's 1.79 x 10⁻⁴ g of He.
To fill a volume of 6.3 L the mass of He required
= 1.79 x 10⁻⁴ g/mL * 6300 mL
= 11 277 * 10⁻⁴ g
Therefore mass of He required = 1.1277 g of He
D- Physical
Explanation:
A physical property is anything that has characteristics associated with a change in it's chemical composition
Answer:
<h2>Organic molecules are important to living things because life is based on the properties of carbon. Carbon is an important element because it can </h2><h2>form four covalent bonds. ... The carbon skeletons contain the functional groups that are involved in biochemical reactions.</h2>

Answer: 104 g
Explanation: reaction Cr2O3 + 3 H2 ⇒ 2 Cr + 3 H2O
M(Cr2O3) = 150 g/mol, so n = m/M = 1.0 mol
Number of moles of H2 should be 3.0 moles and
It is much greater (150 g / 2.016 g/mol)
1 mol Cr2O3 produces 2 mol Cr.
Mass m= 2.0 mol· 52g/mol= 104 g
