Question

what is ratio of water?​

Answer 1

Explanation:

The water–cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix. A lower ratio leads to higher strength and durability, but may make the mix difficult to work with and form. Workability can be resolved with the use of plasticizers or super-plasticizers.

Explanation:

2 molecules of hydrogen ( 1 atomic mass) ( but there are 2 molecules so it will be 2)

1 molecule of oxygen (16 atomic mass)

2/16 = 1/8

1/8 = 1:8
