How many grams are there in 9.03 x 1023 molecules of CO2?
wariber [46]

Answer:

The correct answer is - 66g.

Explanation:

Given:

molecules of CO2 = 9.03 x 10^23

We know:

1 mole of any substance = 6.02x10^23 molecules. (Avogadro's number)

M (CO2) = 12 + (2x16) = 12 + 32 = 44g

Solution:

The mass of CO2 with 9.03x10^23 molecules would be:

44g of CO2 = 6.02x10^23 molecules.

So, the mass in grams of CO2 (X) = 9.03x10^23 molecules

Xg of CO2 = (44x9.03x10^23)/6.02x10^23 = 66g

Thus, the correct answer would be - 66gm.

Find the density of an empty tissue box with a mass of 345 grams and a volume of 1125 cm3.
trasher [3.6K]

Answer:

The answer is

<h2>0.307 g/cm³</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}

From the question

mass of box is 345 g

volume = 1125 cm³

The density of the object is

density =  \frac{345}{1125}  \\  = 0.3066666...

We have the final answer as

<h3>0.307 g/cm³</h3>

Hope this helps you
