as 100 milliliters of 0.10 molar KOH is added to 100 milliliters of 0.10 molar HCL at 298 K, the pH of the res?A. decrease to 3B

Mila [183]

Answer:

C. increase to 7.

Explanation:

Hello,

In this case, the undergoing chemical reaction is:

$KOH+HCl\rightarrow KCl+H_2O$

Thus, the molar relationship is 1 to 1, therefore, the moles are:

$n_{HCl}=0.1mol/L*0.1L=0.01molHCl\\n_{KOH}=0.1mol/L*0.1L=0.01molKOH\\$

Thus, since the entire hydrogen ions are neutralized, the pH C. increase to 7.

Best regards.

What would the total mass of a 4.9 mole sample of Barium (Ba) be if its Molar Mass is 137g?

Aleksandr-060686 [28]

Answer:

m = 671 grams

Explanation:

Given that,

No of moles, n = 4.9

Molar mass of Barium, M = 137 g

Mass divided by molar mass is equal to no of moles. It can be given by the formula as follows :

$n=\dfrac{m}{M}\\\\m=n\times M\\\\m=4.9\times 137\\\\m=671.3\ g$

m = 671 grams

So, the total mass of the sample of Barium is 671 grams.
