The atmospheric pressure will be:
The pressure of the atmosphere resulting from the mercury column is 0.959 atm
What is atmospheric pressure?
The force that an object experiences from the weight of the air above it per unit area are known as atmospheric pressure.
Given: Height of mercury column = 729 mm Hg
To find: The pressure of the atmosphere
Calculation:
The atmospheric column resulting from the mercury column is calculated as follows:
1 atm =760 mm Hg
So, we can convert the 729 mm Hg to atm, and we get
Atmospheric pressure = 729 x 1 atm / 760 = 0.959 atm

The volume in liters of 3245 aluminum cans is 24.8 L.
A recycling center collects 3245 aluminum cans and there are 22 aluminum cans in 1 lb. The mass of 3245 aluminum cans is:
To convert mass to volume, we need the density of aluminum (5.95 lb/L). The volume corresponding to 147.5 lb of aluminum is:
The volume in liters of 3245 aluminum cans is 24.8 L.

KE = 1/2 * m * v^2
KE = 1/2 * 130 * 23^2
KE = 34385J
Answer:
Required Volume is 22.47ml
Explanation:
To make 2.0L of 0.2M sulfuric acid required moles = 0.2 x 2 = 0.4 moles
To get 0.4 from 17.8M required quantity = 1000/17.8 x 0.4 = 22.47ml
