The balanced equation is <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/ead8f365a0b4bd05fdb1db8a2cc8e0ea-.png" /> The product ' X ' is H 3 PO 4. Molecular mass =[3 × 1]+[1 × 31]+[4 × 16] =98 u

Q. What is the molecular mass (in amu) of the product ' $X$ ' in the following unbalanced chemical equation?
$P_{4} + (Hot conc) H N O_{3} ⟶ X + N O_{2} + H_{2} O$
[Given At. Wt.: $P = 31 u, H = 1 u, N = 14 u, O = 16 u$ ]

The balanced equation is

The product ' $X$ ' is $H_{3} P O_{4}$ .
Molecular mass $= [3 \times 1] + [1 \times 31] + [4 \times 16]$
$= 98 u$

Q. What is the molecular mass (in amu) of the product ' X ' in the following unbalanced chemical equation? P4​+(Hot conc)HNO3​​⟶X+NO2​+H2​O [Given At. Wt.: P=31u,H=1u,N=14u,O=16u ]

The balanced equation is The product ' X ' is H3​PO4​. Molecular mass =[3×1]+[1×31]+[4×16] =98u

Q. What is the molecular mass (in amu) of the product ' $X$ ' in the following unbalanced chemical equation?
$P_{4} + (Hot conc) H N O_{3} ⟶ X + N O_{2} + H_{2} O$
[Given At. Wt.: $P = 31 u, H = 1 u, N = 14 u, O = 16 u$ ]

The balanced equation is

The product ' $X$ ' is $H_{3} P O_{4}$ .
Molecular mass $= [3 \times 1] + [1 \times 31] + [4 \times 16]$
$= 98 u$
