I will assume here that we know the molar mass of sulfur, which is 32 g/mol (around).

this means that 0.5 moles will have half of it - the first option is correct!
8 moles will have 8 times this, which is 256 - the second option is not correct!
3 moles would have 96 grams -third option is not correct!
and we also know that 96 grams can't be 4 moles - so the forth option is not correct either

You plan to go snowboarding this weekend in Pennsylvania. The resort charges $15.75 per hour in addition to a $25 deposit to ren

erica [24]

Answer:

$88 in total

Step-by-step explanation:

x = number of hours

y = total cost to rent the snowboard.

$25 is already guaranteed

25 + 15.75x = y

since it is 4 hours from 8:30 a.m. to 12:30 a.m. you put 4 into x.

25+15.75(4) = y

88 = y
