How many molecules are in 100 g of C6H120,?*​
Grace [21]

Answer:

3.37 × 10²³ molecules

Explanation:

Given data:

Mass of C₆H₁₂O₆ = 100 g

Number of molecules = ?

Solution:

Number of moles of C₆H₁₂O₆:

Number of moles = mass/molar mass

Number of moles = 100 g/ 180.16 g/mol

Number of moles = 0.56 mol

Number of molecules:

1 mole contain 6.022 × 10²³ molecules

0.56 mol × 6.022 × 10²³ molecules /1 mol

3.37 × 10²³ molecules

How much salt (NaCl) is carried by a river flowing at 30.0 m3/s and containing 50.0 mg/L of salt? Give your answer in kg/day.
ser-zykov [4K]

Answer:

129,600kg/day

Explanation:

The river is flowing at 30.0m^{3}/s

1m^{3}/s = 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= \frac{ 2,592,000,000*50}{1}

X= 129,600,000,000 mg/day

convert this value to kg/day by multiply by 10^{-6}

X= 129,600kg/day
