Mekhanik [1.2K]3 years ago
7 0

Answer:

Number of moles = 0.31 mol

Explanation:

Given data:

Mass of H₃PO₄ = 30.0 g

Number of moles = ?

Solution:

Formula:

Number of moles = mass/ molar mass

Molar mass of H₃PO₄ = 98 g/mol

Number of moles = 30.0 g / 98 g/mol

Number of moles = 0.31 mol

Why are environmental factors important to consider when assessing an individual’s health?
lisabon 2012 [21]

Answer: c. Some health risks are increased by heredity, which manifest under certain environmental conditions.

Explanation:

Many abiotic factors (non-living factors) such as radiations, hazardous substances present in the environment such as air, water and soil may originate from the industries, mining practices, fossil fuels and landfills. Some of the substances are carcinogenic and mutagenic in nature. These are capable of affecting the genetic make up of the organism. The genetic variations or mutations occurs may transmit from the parent to the offsprings.

Therefore, on the basis of the above information, c. Some health risks are increased by heredity, which manifest under certain environmental conditions. is the correct option.

How many grams is 4.2X10^24 atoms of sulfur?
ipn [44]
First find the number of moles of sulfur using dimensional analysis with avogadro’s number as the conversion factor. 4.2*10^24 atoms * (1 mol/6.022*10^23 atoms) = 7.0 mol sulfur. The molar mass of sulfur is 32.06 g/mol, which is found on the periodic table as sulfur’s (S) atomic weight. Use dimensional analysis again with the molar mass of sulfur as the conversion factor. 7.0 mol * 32.06 g/mol = 224.42 g sulfur. Since the problems gives us two significant figures, round the mass of sulfur to 220 grams, or 2.2 * 10^2 g.
