A 9.168 M aqueous solution of H2SO4 has a density of 1.4987 g/mL at 20°C.
a. How many grams of H2SO, are in 50.0 g of this solution?
b. What is the percent by mass of this solution?
c. From the answer to (b) we see that H2SO4 is the solvent
and H2O is the solute. What is the molarity of water in
this solution?
d. What is the molality of this solution?
e. What is the osmotic pressure of this solution?

What property of the wave is labeled H?

amplitude

crest

wavelength

trough I S T H A T T H E

Explanation:

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
