What is the percent by mass of water in Na2SO4 • 10H2O? Use mc003-1. Jpg. 5. 59% 11. 26% 44. 08% 55. 92%.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
