5. How many mm are equal to 4.75 x 10-2 m?
liq [111]

Answer:

47.5 mm are equal to 4.75 × 10⁻² m.

Explanation:

Meter and millimeter both are units of length. Millimeter is smaller unit while meter is larger unit. The one meter consist of thousand millimeter or we can say that one thousand millimeters are equal to one meter. In order to convert the meter value into millimeter we have to multiply the values with thousand.

we know that one meter is equal to 1000 millimeter.

1 m = 1000 mm

4.75 × 10⁻² × 1000 = 47.5 mm

47.5 mm are equal to 4.75 × 10⁻² m.

What is the empirical formula of a substance that contains 2.64 g of c, 0.444 g of h, and 7.04 g of o?
vitfil [10]

To calculate empirical formula, number of moles of different atoms calculated first:

Number of moles of Carbon , n=  

=\frac{Given mass of carbon}{Molar mass of carbon}

=\frac{2.64 g}{12.011 g mol^{-1}}

= 0.220 mol  

Number of moles H =\frac{Given mass of hydrogen}{Molar mass of hydrogen}

=\frac{0.444 g}{1.008 g mol^{-1}}

= 0.440 mol

Number of moles of oxygen =\frac{Given mass of oxygen}{Molar mass of oxygen}

=\frac{7.04 g}{15.999 g mol^{-1}}

= 0.440 mol

Ratio of carbon

=\frac{0.220}{0.220}

= 1

Ratio of hydrogen

=\frac{0.440}{0.220}

= 2  

Ratio of oxygen

=\frac{0.440}{0.220}

= 2  

So, the empirical formula is CH₂O₂
