Hey there!
It's hydrogen. As number one on the periodic table, it's <em><u>everywhere.</u></em><u /> This is likely because it's the simplest element- made of just one proton and one electron. It's said that 90 percent of the visual universe is made of hydrogen.
Hope this helps!
Answer:
the percent of actual fruit juice in the mixture will be 76%
Explanation:
given that we are mixing 2 bottles the total volume the mixture will be
mixture volume = volume bottle 1 + volume bottle 2 = 48 ounces + 32 ounces = 80 ounces
also the total quantity of juice will be
juice mass in mixture = juice bottle 1 + juice bottle 2 = 48 ounces * 1 + 32 ounces * 0.4 = 60.8 ounces of juice
therefore the concentration of juice in the mixture will be
concentration = 60.8 ounces of juice / 80 ounces = 0.76 (76%)
therefore the percent of actual fruit juice in the mixture will be 76%

The number of moles of a gas if it occupy a volume of 4dm at 10 atm and - 200 c is 6.67 moles
calculation
by use of ideal gas equation
that is PV =nRT
where P(pressure) = 10 atm
V( volume) = 4dm^3 = 4L
n(number of moles) =?
R(gas constant) = 0.0821 L.atm/mol.K
T = -200 +273 = 73 K
make n the formula of the subject n = PV/RT
n is therefore = (10 atm x 4l)/(0.0821 L.atm/mol.K x 73 K) = 6.67 moles
