How much ice (in grams) would have to melt to lower the temperature of 354 ml of water from 26 ?c to 6 ?c? (assume the density o
Anit [1.1K]
Heat gained in a system can be calculated by multiplying the given mass to the specific heat capacity of the substance and the temperature difference. It is expressed as follows:<span>

Heat = mC(T2-T1) 

When two objects are in contact, it should be that the heat lost is equal to what is gained by the other. From this, we can calculate things. We do as follows:

<span>Heat gained = Heat lost</span>
mC(T2-T1) = - mC(T2-T1) 

C(liquid water) = 4.18 J/gC
C(ice) = 2.11 J/gC

</span><span>(354 mL)(1.0 g/mL)(4.18 J/gC)(26 C - 6 C) = m(2.11 J/gC)(6 - 0C) </span><span>
m = 2337.63 g of ice

What is the molar mass of CaCl2?
kherson [118]

Answer: The correct option is 1.11\times 10^{2} g/mol

Explanation:

Atomic mass of calcium ,Ca = 40.07 g/mol

Atomic mass of chlorine ,Cl = 35.5  g/mol

Molar mass of CaCl_2:

= (Atomic mass of Ca+2 × (Atomic mass of Cl))

= (40.07 g/mol + (2 × 35.5))=111.07 g/mol

111.07=1.1107\times 10^{2} g/mol\approx 1.11\times 10^{2} g/mol

Hence, the correct option is 1.11\times 10^{2} g/mol
