Determine the final volume of a soccer ball if the initial volume is 10.4 L at 20°C and the ball is taken outside to a temperature of 0°.

What is the molar mass of ca(cio4)2

I'm learning about the periodic tables and what each subject's configuration is. for example, hydrogen is 1s^1, but i don't understand how you get that. can someone me understand how to figure out how to figure this out? sorry if the question makes no sense, but it would really a lot if you could me understand! you so much if you can!

Use the periodic table to find the molar mass of each element. molar mass h = g/mol molar mass s = g/mol molar mass o = g/mol
