Calculate the mass in gram of Na+ in 25g of Na2SO4

8 grams

Explanation:

Finding the mr of each part:

= 23 x 2 = 46

= 32.1 + (16 x 4) = 96.1

Finding the fraction of the compound that is Na+

We now know that per gram, 460/1421g are Na+

In 25g,

So there are 8g Na+

Hope this helps, let me know if you have any questions! :)

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
