A 30.5 gram sample of glucose (c6h12o6) contains ________ atoms of oxygen.
Margaret [11]
First, find the number of moles of glucose in 30.5 g.

You need the molar mass.

Molar mass of C6H12O6 = 6 * 12.01 g/mol + 12 * 1.01 g/mol + 6*16g/mol = 180.2 g/mol

number of moles = mass in grams / molar mass = 30.5 g / 180.2 g/mol = 0.169 mol

Second, use molecular formula

1 mol of C6H12O6 contains 6 moles of O.

Then, 0.169 moles of C6H12O6 contains 6 *0.169 = 1.014 moles of O.

Third, multiply by Avogagro's number:

1.014 moles * 6.022 * 10^23 atoms / mole = 6.106 * 10^ 23 atoms.

Answer: 6.106 * 10 ^23 atoms of oxygen.

Increasing the surface area of the reactants will decrease the rate of the reaction true or false
andrey2020 [161]

Answer:

Increasing the surface area of a reactant increases the frequency of collisions and increases the reaction rate. Several smaller particles have more surface area than one large particle. The more surface area that is available for particles to collide, the faster the reaction will occur.
