Answer:
0.8 mL of protein solution, 9.2 mL of water
Explanation:
The dilution equation can be used to relate the concentration C₁ and volume V₁ of the stock/undiluted solution to the concentration C₂ and volume V₂ of the diluted solution:
C₁V₁ = C₂V₂
We would like to calculate the value for V₁, the volume of the inital solution that we need to dilute to make the required solution.
V₁ = (C₂V₂) / C₁ = (2mg/mL x 10mL) / (25 mg/mL) = 0.8 mL
Thus, a volume of 0.8 mL of protein solution should be diluted with enough water to bring the total volume to 10 mL. The amount of water needed is:
(10 mL - 0.8 mL) = 9.2 mL
a. displacement = 6 km
b. velocity = 4 km/h

Given
a morning paper route
Required
displacement
velocity
Solution
Displacement is a vector quantity that shows changes in the position of objects in a certain interval of time. Displacement has magnitude and direction
Can be simplified displacement = distanced traveled from starting point to ending point
a. Since we only consider the starting point and the end point, we just need to add up the distances to the north
3 km + 3 km = 6 km
b. Velocity = displacement changes with time
Answer:
97.994 g/mol
Explanation:
One molecule of H₃PO₄ contains three atoms of H, one of P, and four of O.
3H = 3 × 1.0079 u = 3.0237 u
1P = 1 × 30.974 u = 30.974 u
4O = 4 × 15.999 u = <u>63.996 u
</u>
Total = 97.994 u
One molecule has a mass of 97.994 u.
One mole has a mass of 97.994 g.
The molar mass of H₃PO₄ is 97.994 g/mol.
