8 0

Answer:

H3PO4 Mol mass..

= (3 x H1 = 3) + (1 x P31 = 31) + (4 x O16 = 64). = 98g/mol.

a)..Hydrogen: = 3 / 98 = 0.0306 x 100% = 3.06%.

b)..Phosphorus = 31/98 = 0.3162 x 100% = 31.63%.

c)..Oxygen = 64/98 = 0.6531 x 100% = 65.31%.

(Total = 100% H3PO4).

Explanation:

Find the molar mass of all the elements in the compound in grams per mole.

Find the molecular mass of the entire compound.

Divide the component's molar mass by the entire molecular mass.

You will now have a number between 0 and 1. Multiply it by 100% to get percent composition.

If you burn 50.6 g of hydrogen and produce 452 g of water, how much oxygen reacted?
Svetllana [295]
Acc. to Law of Conservation of Mass
Mass of reactants=Mass of Products
Let mass of Oxygen be x.
So,
50.6+x=452
x=452-50.6
=401.4 g

how much current would be measured in a circuit if the light bulb has a resistance of 6 ohms and a voltage of 36 volts
Stels [109]

Answer:

The right response is "6 A". A further explanation is given below.

Explanation:

The given values are:

Resistance,

R = 6 ohms

Voltage,

V = 36 volts

As we know,

⇒  V=IR

then,

⇒  I=\frac{V}{R}

On substituting the values, we get

⇒     =\frac{36}{6}

⇒     =6 \ A
