Volume of a gas divided by molar volume = moles
moles x molar mass = mass
5600/22400 = .25
.25 x 48 = 12 g
third
it is more dense think about how heavy the water feels you go down you feel more pressure so it is denser
Answer:
Rocks that undergo a change to form a new rock are referred to as metamorphic rocks. ... Sedimentary rocks were originally sediments, which were compacted under high pressure. Igneous rocks formed when liquid magma or lava—magma that has emerged onto the surface of the Earth—cooled and hardened
Explanation:
Atomic number = 1
Mass number = 1
Proton = 1
Neutron = mass number - atomic number
= 1 - 1
= 0
Answer:
25.2 grams HOAc
Explanation:
For solution preparations a simple formula for determining amount of solute needed is ...
from solid stock => grams = Molarity x Volume (Liters) x formula wt of solute
∴ grams HOAc = M·V·f.wt = (0.839M)(0.500L)(60.05g/mol) = 25.2 grams HOAc
Mixing => Transfer gram wt of solute to mixing container and dilute up to but not to exceed total needed volume.
