Answer:
We need 2.933 L of 0.15 mg /mL of protein solution.
Explanation:
Concentration of given solution
1 mg = 0.001 g , 1 mL = 0.001 L
Molecular weight of protein = 22,000 Da =22,000 g/mol
Initial concentration in moles/liter:
Initial concentration in micromoles/mL :
1 L = 1000 mL
Initial concentration in micromoles/microLiter :
1 L = 1000,000 μL
Moles of protein required = 20 μmoles
n(Moles)=C(concentration) × V(Volume of solution)
We need 2.933 L of 0.15 mg /mL of protein solution.
Answer:
The Equation for this reaction is as follow,
2 Cr(ClO₃)₃ → 2 CrCl₃ + 9 O₂
According to eq,
604.68 g (2mole) of Cr(ClO₃)₃ produces = 288 g (9 moles) of O₂
So,
146.5 g of Cr(ClO₃)₃ will produce = X g of O₂
Solving for X,
X = (146.5 g × 288 g) ÷ 604.68 g
X = 69.77 g of O₂
1. The <span>student with a measurement that might be in centimeters is A. Bill.
2. C</span><span>entimeters in 0.05 kilometers is </span>C. 5,000
solution:
0.05 km x (1000 meters/ 1 km)
= 50 meters x (100 cm/ 1 meter)
=5000 cm
