Answer:
0.7
Step-by-step explanation:
7 x 0.10
=> 7 x 0.1
=> 7 x 1/10
=> 7/10
=> 0.7
Get unknowns on one side and know on other side.
Divide both sides by -2
X= -7
one mole of water contains 6.02 x 1023 MOLECULES of water. But each molecule of water contains 2 H and 1 O atom = 3 atoms, so there are approximately 1.8 x 1024 atoms in a mole of water.
This is pretty much 75% of 55.5 which is 41.625. Rounding that up would make $41.63.
