33.23 grams of a thin sheet of iron is completely oxidized in 7 days. How would you express the rate of conversion of the silver

tresset_1 [31]

Answer:

A. 0.0440 moles/day

Explanation:

First, let's figure out how many moles 33.23 grams of silver is. We do this by dividing the number of grams by the molar mass of silver, which is 107.87 g/mol:

33.23 g Ag ÷ 107.87 g/mol = 0.3081 mol Ag

Now, let's divide this by 7 to get the rate per day:

0.3081 mol Ag ÷ 7 days = 0.0440 mol/day

Thus, the answer is A.

What is the density of a solid that has a mass of 9.2 grams and a volume of 12.3 cm3 ? Would this object float or sink in water?

cluponka [151]

Mass=9.2g
Volume=12.3

$\boxed{\sf Density=\dfrac{Mass}{Volume}}$

$\\ \sf\longmapsto Density=\dfrac{9.2}{12.3}$

$\\ \sf\longmapsto Density=0.74g/cm^3$

Density of water =1g/cm^3

It will float in water
