Answer:

The molarity of the HCl solution is 0.17M

Explanation:

When a titration occurs between an acid and a base it is called neutralization.

The formula to calculate the concentration of the acid is:

Ca*Va=Cb*Vb

where Ca and Cb are the concentrations of the acid and the base respectively and Va and Vb are the volumes of the acid and the base.

As HCl is an acid, solve the equation for Ca:

Ca=\frac{Cb*Vb}{Va}

Replacing values:

Ca=\frac{0.2MNaOH*11.1mLNaOH}{13.0mLHCl}

Ca=0.17M

Therefore the molarity of the HCl solution is 0.17M

A scientist digs up sample of arctic ice that is 458,000 years old. He takes it to his lab and finds that it contains 1.675 gram
Fiesta28 [93]

Answer:

6.70 grams of krypton-81 was present when the ice first formed

Explanation:

Let use the below formula to find the amount of sample

N= N_0(\frac{1}{2})^n

where

n = \frac{t}{t_{\frac{1}{2}}}

here

t =  458,000 years

t_{\frac{1}{2}} = 229,000

\frac{t}{t_{\frac{1}{2}}} = \\frac{ 458,000}{229,000}

n = \frac{t}{t_{\frac{1}{2}}} = 2.000

Now substituting the values

1.675 = N_0(\frac{1}{2})^{2.000}}

1.675 = N_0\times (0.2500)

N_0= \frac{1.675}{0.2500}

N_0=6.70
