1) We need to find mass of the solution
m=D*V
D= <span>1.725 g/mL
V= 250 mL
m=</span>1.725 g/mL*250 mL= 431.25 g
2) 75% = 0.75
0.75*431.25 ≈ 323 g of NH4NO3

Answer:
Iodine
Explanation:
Iodine is in group 17 on the periodic table (first picture attached). The second picture shows you in the top left-hand corner of Iodine's little square, there is the number 53. This is the atomic number, it is also the number of protons and electrons in an element.
Hope this helped :)
Answer:
163 L
Explanation:
To find the volume, you need to use the Ideal Gas Law. The equation looks like this:
PV = nRT
In this equation,
-----> P = pressure (atm)
-----> V = volume (L)
-----> n = moles
-----> R = constant (0.0821 L*atm/mol*K)
-----> T = temperature (K)
Before you can plug the given values into the equation, you first need to convert Celsius to Kelvin.
P = 3.50 atm R = 0.0821 L*atm/mol*K
V = ? L T = 75.3 °C + 273.15 = 348.45 K
n = 20.0 moles
PV = nRT
(3.50 atm)V = (20.0 moles)(0.0821 L*atm/mol*K)(348.45 K)
(3.50 atm)V = 572.1549
V = 163 L
