Answer:

about 3.937

Explanation:

There are exactly 2.54 cm in an inch so we have

10cm/1 * 1inch/2.54cm = 10inch/2.54 = 3.937

Convert 4 x 10^-3 dL to cm^3 <br><br> Please give the work and the answer in scientific notation.
Serhud [2]

4 x  10^{-3 in dL will be 4 x  10^{-1}  cm^3

<h3>Conversion from dL to cm^3</h3>

Recall that:

Deci = 10^{-1}

Centi = 10^{-2}

Thus, 1 dl = 100 ml

This means that converting from dl to  cm^3 requires multiplying by 10^2.

Applying this principle, 4 x 10^{-3 in dL to  cm^3 will be:

4 x 10^{-3 x  10^2 cm^3 = 4 x  10^{-1}  cm^3

Therefore,  4 x 10^{-3 dl will be 4 x  10^{-1}  cm^3

How many grams would 1.00 billion atoms of sulfur weigh
Zielflug [23.3K]

Answer:

m_S=5.31x10^{-14}gS

Explanation:

Hello,

In this case, by knowing that we have 1 billion ( 1,000,000,000) of atoms of sulfur, via the Avogadro's number we can firstly compute the moles:

n_S=1,000,000,000atoms*\frac{1mol}{6.022x10^{23}atoms}\\\\ n_S=1.66x10^{-15}molS

Then, by using the atomic mass of sulfur (32 g/mol), we can finally compute the mass:

m_S=1.66x10^{-15}molS*\frac{32gS}{1molS}\\ \\m_S=5.31x10^{-14}gS

Best regards.
