an empty jar weighs 1.43 pounds. How much will it weigh when 1.00L of homgenized milk is poured into it? trhe density of homogenized milk is 1.03g/ml. (1 pound= 453.6g)

an empty glass tube weights 37.3 g. when filled to the rim with water is weighs 54.1g. what is the volume of the glass tube?

what mass of water at 10.0 degrees C is needed to cool 500.0ml of tea from 25.0 degrees C to 18.3 degrees C? Density and specific heat of the tea are the same as water.

what will be the final temperature of a system in which 150.0g of water at 5.0 degrees C are added to 1.00L of water at 90.5 degrees C?

based on the following chemical equation HCN+O2 yields N2+CO2+H20 identify the limiting reactants and the mass of N2 produced when 100.0g of HCN react with 100.0g of O2. a. the limiting reactant is HCN and 25.9g of N2 are produced b. the limiting reactant...

assume equal masses of the following substances, all of them at 20.0 degrees C and exposed to the same source of heat simultaneously. Which substance will reach a temp of 35.0 degress faster? aluminium sp 0.900 lead sp 0.128 titanium sp 0.523 tin sp 0.222

what mass of sodium chloride will be required to completely react with 4.00 x 10(24) units of AgNO3 and form AgCl and sodium nitrate?

a gas misture containing N2 and O2 was kept inside a 2.00 L container at a temp of 23.0 degrees C and a total pressure of 1.00atm. The partial pressure of O2 was 0.722atm. How many grams of Nitrogen were present in the mixture?

Convert 1.43 pounds to grams. =648.648g 1,000 mL milk x 1.03 g/mL = g milk. =1030 g jar + g milk = total grams. Does the jar weigh 2.27 pounds when filled with milk then?

Thanks....I did that one right.

Disregard...I got it. 3.70 pounds

Got it....thanks Dr Bob

150.0g x 4.184x(85.5)= 53659.80 + 1000ml x 4.184x 5 = 20920 74579.80 / 4.184= I DON'T GET IT!

This makes sense. Thank you so much. This a great website. I don't just want someone to tell me the answer....I want to know how to figure it out. Thanks.

(? x 4.184 x 6.7) = (500 x 4.184 x 8.3) 28.03x = 17363.6 x= 6.19 x 10(2)g is this correct?

and which one will take the longest time to heat up to 35.5 degrees C?

Balanced equation is: NaCl + AgnO3 yields AgCl + NaNO3 1mol 1 mol 1 mol 1 mol NaCl= 58.44 This is as far as I get. My answer choices are: 6.64g 0.144g 388g 8.80g
