The mass of hydrogen in 57.010 g ammonium hydrogen phosphate, (NH₄)H₂PO₄ is 2.97 g
<h3>Determination of mass of 1 mole of (NH₄)H₂PO₄ </h3>
1 mole of (NH₄)H₂PO₄ = 14 + (4×1) + (2×1) + 31 + (16×4) = 115 g
<h3>Determination of the mass of H in 1 mole of (NH₄)H₂PO₄ </h3>
Mass of H = 6H = 6 × 1 = 6 g
<h3>Determination of the mass of H in 57.010 g of (NH₄)H₂PO₄ </h3>
115 g of (NH₄)H₂PO₄ contains 6 g of H.
Therefore,
57.010 g of (NH₄)H₂PO₄ will contain = (57.010 × 6) / 115 = 2.97 g of H
Thus, 2.97 g of Hydrogen, H is present in 57.010 g of (NH₄)H₂PO₄

The volume of the prism is the amount of space on the prism
The volume of the cylinder is 760 cubic units
<h3>How to determine the volume?</h3>
The question is incomplete.
So, we make use of the following parameters
- Shape = Cylinder
- Radius, r = 11
- Height, h = 2.
The volume of a cylinder is calculated using:
V = πr²h
Substitute known values in the above formula
V = 3.14 * 11² * 2
Evaluate the product
V = 759.88
Approximate
V = 760
Using the assumed values, the volume of the cylinder is 760 cubic units

Assuming a student pushes a 51. 5 kilogram bookshelf across a smooth floor with a net force of 67 n the acceleration is 1.30m/s².
<h3>Acceleration</h3>
Using this formula
Acceleration= Net force/Mass of bookshelf
Where:
Mass of bookshelf =51.5 kilogram
Net force =67 Newton
Let plug in the formula
Acceleration=67n/51.5 kilogram
Acceleration=1.30 m/s²
Inconclusion the acceleration is 1.30m/s².
