Answer:
357.475
Explanation:
First you need periodic table and you have to look for mass
Fe = 3 x 55.845 = 167.535
P = 2 x 30.97 = 61.94
o = 4 x 2 so 8 oxygen = 8 x 16 = 128
add all and you get 357.475
Answer: Objects with like charge repel each other.
Answer:
Volume = 13.06 L
Explanation:
We are given: mass of nitrogren gas = 16.34 g
We know: molar mass of nitrogen gas = 28.014 g/mol
: ideal gas law constant = 0.082 L.atm/K.mol
At STP: temperature = 273.15 K
: pressure = 1 atm
We first determine the number of moles of nitrogen gas:
n = m/M
= 16.34/28.014
= 0.58 mol
Using the ideal gas law:
Answer:
answer
Explanation:
assumes that the molecules are very small relative to the distance between molecules. The molecules are in constant, random motion and frequently collide with each other and with the walls of any container. ... The higher the temperature, the greater the motion.
