Answer:
129,600kg/day
Explanation:
The river is flowing at 30.0[tex]m^{3}/s[/tex]
1[tex]m^{3}/s[/tex] = 1000L
Multiply by 1000 to convert to L/s
flowrate of river = 30*1000 =30,000L/s
Convert L/s to litre per day by multiplying by 24*60*60
flowrate of river = 30,000 * 24*60*60 L/day
= 2,592,000,000L/day
if the river contains 50mg of salt in 1L of solution
lets find how many mg of salt (X) is contained in 2,592,000,000L/day
X= [tex]\frac{ 2,592,000,000*50}{1}[/tex]
X= 129,600,000,000 mg/day
convert this value to kg/day by multiply by [tex]10^{-6}[/tex]
X= 129,600kg/day
