Bonjeur monseur, la french are here! it seems you have a problem with the elements on earth. lead seems correct since it is indeed a harmful material
Answer:
The volume is 59, 3 liters. See the explanation below, please
Explanation:
STP conditions (standard) correspond to 273K of temperature and 1 atm of pressure. These values are used and the volume is calculated, according to the formula:
PV = nRT
1 atm x V= 2, 65 moles x 0, 082 l atm/K mol x 272 K
V= 2, 65 moles x 0, 082 l atm/K mol x 272 K/1 atm = 59, 3 liters
Answer: 2.408×10^24 atoms
Explanation:
Applying the formula
No. moles= (no. Of atoms)/Avogadro's number
4 = n/6.02×10^23
no. of atoms= 2.408×10^24 atoms
Divide the mass of solution by total volume of the solution. formula would be C = M/V (m is mass and v is volume). include the value you found of the mass and volume, then divide them to find the concentration of your solution.
