Answer:
3.125 grams
Explanation:
Applying,
R = (
)R'............... Equation 1
Where R = Original mass of Astatine-211, R' = mass of Astatine-211 left after decay, t = total disintegeration time, n = halflife of Astatine-211
make R' the subject of the equation
R' = R/()............ Equation 2
From the question,
Given: R = 50 grams, t = 28 hours, n = 7 hours
Substitute into equation 2
R' = 50/(
)
R' = 50/(2⁴)
R' = 50/16
R' = 3.125 grams
Answer:
This concentrations represents 9.71 x 10¹⁹ nitrate ions per litre of drinking water.
Explanation:
Nitrate: NO₃⁻
MW = 62.00 g/mol
1 mol = 6.022 x 10²³
62 g NO₃⁻ ____________ 6.022 x 10²³ ions
10 x 10⁻³ g NO₃⁻ _________ x
x = 9.71 x 10¹⁹ ions
This concentrations represents 9.71 x 10¹⁹ nitrate ions per litre of drinking water.
