Thermochemistry question?

Which requires more heat to warm from 25C to 85C, 60g of water or 95.5g of ethylene glycol (specific heat = 2.39J/gC

So i used q=mst for each

(60g)(60C)(4.18) = q = 15048

(95.5g)(60C)(2.39) = q = 13694.7

so from this would the answer have the lower q? enthylene glycol?

water requires 15048 J (a measure of heat required)
ethylene glycol requires 13695 J
water requires more heat (15048 J vs. 13695 J)

Yes; ethylene glycol takes less heat; the water takes more heat.
