Answer:

31.99 g O2

Explanation:

Any gas at STP has a molar volume of 22.4 L/mol. This may be an amount you want to memorize.

 

(given volume) * (molar volume)= moles of O2

22.4 L * \frac{1 mol}{22.4 L}= 1 mol O2

Now we can convert moles of O2 to grams using the molar mass of O2.

(moles of O2) * (molar mass of O2)= grams of O2

1 mol * \frac{31.99 g}{1 mol} = 31.99g

Convert 675 nanograms to milligrams.
STALIN [3.7K]

675 nanograms is equivalent to 6.75 × 10-⁴ milligrams.

<h3>How to convert nanograms to milligrams?</h3>

Nanograms is a unit of mass equal to 0.000000001 grams and has a symbol of ng.

On the other hand, milligrams is another unit of mass equal to 0.001grams and has a symbol of mg.

Nanograms and milligrams are both units of mass and can be inter-convertible as follows:

1 nanogram = 1 × 10-⁶ milligram

According to this question, 675 nanograms is equivalent to 675 × 10-⁶ milligrams.

Therefore, 675 nanograms is equivalent to 6.75 × 10-⁴ milligrams.
