The first one is the correct answer
Answer: B.The atoms ⚛️ in Damien’s candy are vibrating faster ❣️ Yur Welcome
It should be about 0.586620881 kilograms
Answer:
By designing new technology that would prove new information
Explanation:
write the equation for the reaction
that is 6 F2 +P4 =4 PF3
find the theoretical mass that is
let the theoretical yield be represented by y
theoretical yield = 78.1/100 = 120/y
y= 153.6 grams
find the number of moles of PF3
moles = mass/molar mass
= 153.6/87.97 =1.746 moles
by use of mole ratio between F2 :PF3 which is 6:4 the moles of F2 is therefore= 1.746 x 6/4 = 2.62 moles
mass = moles x molar mass
= 1.746 moles x38 g/mol = 99.6 grams
