Calculate the mass in grams for 3.28 moles of O2? Please show your work to receive credit.

105 g O₂

Explanation:

Step 1: Define

Molar Mass O - 16.00 g/mol

Molar Mass O₂ - 2(16.00) = 32.00 g/mol

Step 2: Use Dimensional Analysis

= 104.96 g O₂

Step 3: Simplify

We are given 3 sig figs.

104.96 g O₂ ≈ 105 g O₂

s too much pool water may lead to chlorine poisoning. the concentration of chlorine in public drinking water is extremely low and not harmful to human health. sooo yeahh

explanation:

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
