Research shows that the combination of __________ and __________ can reduce the risk of death in a collision by up to 80%
r-ruslan [8.4K]
The combination of seatbelts and airbags can reduce the risk of death in a collision by up to 80%.

The seatbelts help to keep the person in one position and prevent impact with the vehicle as the vehicle comes to a sudden stop. Moreover, the airbag increases the time of collision to reduce the impact experienced by the person. An increased time of collision greatly reduces the damage that is done to the body.

How many grams of MgCl2 would be needed to make 5.3 liters of a 0.25 molar solution? Round your answer to the nearest 0.01,
GuDViN [60]

Answer: 126.1 grams of are needed to make 5.3 L of 0.25 M solution

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

To calculate the mass of solute for given molarity, we use the equation:

\text{Molarity of the solution}=\frac{\text{given mass of solute}}{\text {Molar mass of solute}\times \text{Volume of solution in L}}

0.25M=\frac{x}{95.2g/mol\times 5.3L}

x=126.1g

Thus 126.1 grams of are needed to make 5.3 L of 0.25 M solution
