Question

If you perform the experiment described in investigation #15 by mixing 10 g of glue with 13 g of water and 8 g of sodium borate suspended in 11 g of water, what will be the mass ratio of the materials?

Answer 1

10 g of glue with 13 g of water ,

Mass ratio of the material can be calculated as:

`(Mass of glue)/(Mass of glue + Mass of water)`

`(10 g)/(10 g + 13 g )`

`(10 g)/(23 g )`

8 g of sodium borate suspended in 11 g of water, mass ratio can be calculated as:

`(Mass of sodium borate)/(Mass of sodium borate + Mass of water)`

`( 8 g)/( 8 g + 11 g )`

`(8 g)/(19 g )`
