Step-by-step explanation:

\\  9 \frac{6}{7}  \div 3

<u>Change</u><u> </u><u>the</u><u> </u><u>mixed</u><u> fraction</u><u> </u><u>into</u><u> </u><u>improper</u><u> fraction</u><u>.</u>

<u>\\  =  \frac{69}{7}  \div 3</u>

<u>R</u><u>eciprocal </u><u>3</u><u> </u><u>for</u><u> </u><u>cross</u><u> </u><u>multiplication</u><u>.</u>

<u>\\  =  \frac{69}{7}  \times  \frac{1}{3}</u>

<u>D</u><u>ivide </u><u>6</u><u>9</u><u> </u><u>by </u><u>3</u><u>.</u>

<u>\\   = \frac{ \cancel{69}}{7}  \times  \frac{1}{ \cancel{3}}</u>

<u>\\  =  \frac{23}{7}</u>

<u>Divide</u><u> the</u><u> </u><u>result </u><u>into</u><u> </u><u>mixed</u><u> fraction</u><u> </u><u>or </u><u>decimal.</u>

<u>\\  = 3.285 \:  \: or \:  \: 3 \frac{2}{7}</u>

Suppose that 1 kg of Sodium-24 is reduced to 0.0156 kg in 90 hours. What is the half-life, in hours, of Sodium-24?​
N76 [4]

Answer:

14.99 hours

Step-by-step explanation:

The formula for half-life is given as,

R/R' = 2ᵃ/ᵇ...................... Equation 1

Where R= Original mass of sodium-24, R' = mass of Sodium-24 after disintegration, a = Total time taken for sodium-24 to disintegrate, b = half-life of sodiun-24.

Given: R = 1 kg, R' = 0.0156 kg, a = 90 hours

Substitute into equation 1 and solve for b

1/(0.0156) = 2⁹⁰/ᵇ

Taking the log of both side

log[1/(0.0156)] = log(2⁹⁰/ᵇ)

log[1/(0.0156)] = 90/b(log2)

90/b = log[1/(0.0156)]/log2

90/b = 6.0023

b = 90/6.0023

b =  14.99 hours

b = 14.99 hours.

Hence the half-life of Sodium-24 is 14.99 hours
