Non metals and metollids in periodic tables are the same how this helps ;)
1 mol of Br = 79.9 g
15.7 g / 79.9 g = 0.196 moles of atoms
Hello there.
<span>What is an acid according to Arrhenius?

Answer:
500g because 300g is less dense than 500g its kinda like a weight

Answer:
STP conditions imply a temperature of 273.15 K and a pressure of 100 kPa. When tose conditions are met, 1 mole of any ideal gas will have a volume of 22.7 L. So, if 1 mole occupies a volume of 22.7 L, 2 moles will occupy a volume twice as big. Likewise, 0.5 moles will occupy half the volume 1 mole occupies. Assuming that the gas is at standard temperature and pressure (STP), one mole of any gas occupies 22.4 L . This means the number of moles of O2 is 222.4=0.089 mol .
