Intro to chemistry
a salt solution has a density of 1.15 g/mL and a volume of 0.425L. what is the mass in kg of this solution? I just need to know how to do it period

Chemistry
10.0 g of an unknown acid is titrated to the equivalent point using 65.0 ml of 0.150M KCH. Assuming the acid is monoprotic ( like HCL or HF ) , what is the molecular mass of the acid? Is it possible to find the mols of the acid? (Balanced equation & solution please!)

Chemistry
What volume of .300M HCL is required (a) to titrate 50.0 ml of 0.600 M LiOH? (B) to titrate 50.0ml of .600M Ca(OH)2 (balanced equation and solution for both please!)

Chemistry
What is the molarity of an Acetic Acid Solution that requires 40.0 ml of 0.100M NaOH to titrate a 20.0ml sample to the end point? (Balanced equation & solution please! Thanks in advance)

What is 4x1 1/2?

all the angles on a triangle egual 180 degrees so take 68 times 2 then subtract that by 180

In the following system of equations, what does x equal? -10x - 2y = 56 6x - 2y = -40 x = 6 or x = -6 or x = 2 or x = -2

15. In the following system of equations, what does x equal? -10x + 4y = -64 -10x - 8y = -112

math
first you would want to get the denomonators the same. then it will be easyier to find the answer.

math
you would take 3/4 and multiply it by six or to make it easyier just take the three and add it six times which is 18 thn you take 18 and divide it by 4 which you cant evenly so take 18/4 and reduce it which is 4 cup and 2/4 or 1/2

is mu friction? .24?

Physics
i guess i'm just confused on the mu means static friction? .24?

Physics
thank you, but i am exteremly confused! so i just use PE spring to find d?

Physics
I THINK SOMEONE HAS THIS SAME QUETION! A massless spring of constant k = 91.0 N/m is fixed on the left side of a level track. A block of mass m = 0.50 kg is pressed against the spring and compresses it a distance of d. The block (initially at rest) is then released and travels...
