Answer:
261.337 g/mol
Explanation:
Please mark brainliest my answer got taken down its correct
The solution needed is prepared as below
by use of the M1V1 =M2 V2 formula where
M1 = 2.25 L
v2 = 1.0M
M2 = 9.0 M
V2 =? l
make V2 the subject of the formula V2 =M1V1/M2
= 2.25 L x 1.0M/9.0 M = 0. 25 L
therefore the solution need 0.25 L of 9.0M H3PO4 and dilute it a final volume of 2.25 l
Answer:
Gases have mass, because they are made up molecules which have mass
Sedimentary rocks have layers because of different depositions of sediments over time.
