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 independent variable is the presence/absence of nets; while the dependent variable is the number of berries.
<h3>What is an independent variable?</h3>
In experiments, an independent variable is an element the researcher is manipulating on purpose. In the case of the farmer, the element that is being manipulated is the use of nets.
Therefore, the independent variable will be the presence/absence of nets in each row of bushes.
<h3>What is a dependent variable?</h3>
On the other hand, a dependent variable is a factor affected by the independent variable. In this case, it is expected the use of nets increases the number of berries the farmer can collect.
This means the dependent variable is the number of berries.
