Question

The ratio of hydrogen to oxygen in water is 1:8 by weight. How many grams of hydrogens is there in 1800 grams of water?​

Answer 1

Answer:

Hydrogen and oxygen combine in the ratio of 1:8 by mass to form water.

Step-by-step explanation:

Answer 2

Given data,

The ratio of water and oxygen in water is $1:8$

Let the weight of hydrogen be $1x=x$

Let the weight of oxygen be $8x$

The total weight of the water is given as $1800grams$

That can be written as,

$x+8x=1800$

$9x=1800$

Move nine to RHS from LHS we get,

$x=\frac{1800}{9}$

Also, $1800$ can be written as $9\times 200$

$x=\frac{9\times200}{9}$

The value nine in both numerator and denominator get cancelled.

We get it as,

$x=200grams$

Therefore, the weight of hydrogen in $1800grams$ of water is $200grams$
