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

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

explanation:

r just means there's a number of carbon in teh chain. for example rcooh means that after x number of carbon, the chain ends with cooh.
