<span>Avogadro's number represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole. This number can be used to convert the number of atoms or molecules into number of moles.

 </span><span>7.5 X10^23 molecules of H2SO4 ( 1 mol / 6.022x10^23 molecules ) (98.08 g / 1 mol ) = 122.15 grams H2SO4</span>

Answer : The mass of H_2SO_4 are, 117.6 grams.

Explanation :

First we have to calculate the moles of H_2SO_4.

As, 6.022\times 10^{23} molecules of H_2SO_4 present in 1 mole of H_2SO_4

So, 7.5\times 10^{23} molecules of H_2SO_4 present in \frac{7.5\times 10^{23}}{6.022\times 10^{23}}=1.2 mole of H_2SO_4

Now we have to calculate the mass of H_2SO_4.

\text{Mass of }H_2SO_4=\text{Moles of }H_2SO_4\times \text{Molar mass of }H_2SO_4

Molar mass of H_2SO_4 = 98 g/mole

\text{Mass of }H_2SO_4=1.2mole\times 98g/mole=117.6g

Therefore, the mass of H_2SO_4 are 117.6 grams.

ololo11 [35]

Answer: Option B

Explanation:

Dead space is the volume of sir in the body which is inhaled but it does not takes part in the gaseous exchange this is because it does not contains alveoli.
