So if they fall, the padding will protect their neck or body part so they will not hit hard against the hard wooden or tile floor.
Answer:
d. 1.20 ×10^3 mL
Explanation:
That is the answer have a wonderful day!!
The answer to this is 'No work has been done to the box' Just took the quiz and it's correct
Hey there!:
1 mole of FeSO4 = 151.8 g/mol
25.0 g change to mole = 25.0 / 151.8
moles of FeSO4 = 0.165 moles
One mole of any substance has 6.02*10²³ units
0.165 moles to get the number of Fe ( II ) ions :
number of Fe(II) ion = 0.165 * ( 6.02*10²³ )
number of Fe ( II ) ion = 9.93*10²² units
Solution;
The gas is at STP;
Where; T = 273 K , P = 1 atm
We know that 1 mole of a gas at STP occupies a volume of 22.4 liters .
V1/n1 = V2/n2
n2 = (V2/V1) n1
n2 = (2 l/22.4 l)(1 mole)
n2 = 0.0893 moles
But 1 mole of a compound has 6.022 × 10^23 molecules
Thus, number of molecules = 0.0893 moles × 6.022 ×10^23 molecules
= 5.378 × 10^22 molecules.
