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:    

$\frac{Mass of glue}{Mass of glue + Mass of water}$  

$\frac{10 g}{10 g + 13 g }$  

$\frac{10 g}{23 g }$

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

$\frac{Mass of sodium borate}{Mass of sodium borate + Mass of water}$  

$\frac{ 8 g}{ 8 g + 11 g }$  

$\frac{8 g}{19 g }$
