You have 80 grams of a radioactive kind of vanadium. How much will be left after 48 days if it’s half-life is 16 days?

Tresset [83]

10 grams Vanadium will be left after 48 days

Further explanation:

Half-life is the time after which the chemical is reduced to half.

The reaming mass after half life is given by:

$mass\ fater\ half\ life=\frac{Original\ mass}{2}$

The formula for calculating the remaining mass after given time period is:

$Remaining\ substance=\frac{1}{2^n}*mass$

Here n is the number of half lives passed

Now,

Given

Mass=80 grams

Time= 48 days

Half-life = 16 days

The number of half lives will be:

$n=\frac{48}{16}=3$

Putting the values of n and mass in the formula

$Remaining\ substance=\frac{1}{2^3}*80\\=\frac{1}{8}*80\\=10\ grams$

10 grams Vanadium will be left after 48 days

Keywords: Half-life, radioactive

If you eat a diet with 2,000 kilocalories and 45 percent of those calories come from protein, about how many grams of protein di

jekas [21]

The amount of Protein intake is 900 kilocalorie.

We have - 2000 Kilocalories of diet and 45 Percent of calories come from Proteins.

Wе have to find out the amount of protein intake.

<h3>If ' x ' students out of total ' n ' students in a class are infected by virus. Then, what percentage of students are infected.</h3>

Percentage of students affected are - $\frac{x}{n} \times 100$

In the question given -

Let the amount of Protein intake be y.

Then -

45 = y % of 2000

45 = $\frac{y}{2000} \times100$

y = $\frac{45\times2000}{100}$

y = 900 Kilocalorie

Hence, the amount of Protein intake is 900 kilocalorie.
