The equation would be 4.0cm^3 x 2.7 because for the formula, you need to find the amount of total centimeters and multiply it by 2.7 for each centimeter. 4.0^3 is 64, so the equation would be 64 x 2.7. Do the rest of it and your answer is 172.8
Answer: 8.31

Answer:
in non-metal elements the electrons are held much more tightly in the chemical bonds that hold the atoms together
Answer:
Explanation:
Hello,
In this case, considering that the compound is 48% oxygen, we infer it is 52% chromium, therefore, by using their atomic masses we compute the moles by assuming those percentages as masses:
Next, by dividing by the smallest moles, we find the subscripts in the empirical formula:
Which are also expressed in the smallest whole numbers, therefore the empirical formula is:
Which corresponds to the chromic oxide or chromium (IV) oxide.
