2x-1≤x+5
2x≤x+6
x≤6
uhhh I hope that was easy to follow and it helped. anyways, just pretend the ≤ is a = and solve
Answer:
43.18 gm
Explanation:
Heat of fusion of water at 0° C is 334 j/gm
then you have to heat the water to boiling point (100 C)
specific heat of water is 4.186 j/g-c
x = grams of water
x ( 334 + 4.186 (100) ) = 32500
x = 43.18 gm
Mass number is the total number of Protons and Neutrons. Simply subtract 85 from 210. 210-85=125 neutrons
