Answer: The molar mass of water in the hydrate is 126.14.
Explanation:
7 is atomic symbol 9 is atomic density 8 is the atomic number
Is that chemistry?
Cause I'm kinda confused about how to help you with this question
I believe the correct answers from the choices listed above are the second and the last option. At constant pressure, the systems 2A(g) + B(g) ---> 4C(g) and 2C(g) A(s) + B(s) ---> C(g) produces work to the surroundings. <span>When a gas is evolved during a chemical reaction, the gas can be imagined as displacing the atmosphere - pushing it back against the atmospheric pressure. The work done is therefore V*P where V is the volume of gas evolved, and P is the atmospheric pressure. </span>
<u>Answer:</u> The volume of given mas of tin block at STP is 
<u>Explanation:</u>
To calculate volume of of the substance, we use the equation:

We are given:
Mass of tin = 95.04 g
Density of tin = 
Putting values in above equation, we get:

Hence, the volume of given mas of tin block at STP is
