How many atoms are there in 122 grams of cu(no3)2?.

What’s the percent by mass of carbon in c10h14n2

When 225mg of anthracene, c14h10(s), was burned in a bomb calorimeter the temperature rose by 1.75k. calculate the calorimeter constant. by how much will the temperature rise when 125mg of phenol, c6h5oh(s), is burned in the calorimeter under the same conditions? (δch< (c14h10,s)=–7061 kj mol−1.)

Needthe meter is the standard unit for: 1) height 2) length 3) weight 4) mass
