What is the final volume in milliliters when 0.700L of a 46.9% (m/v) solution is diluted to 20.1% (m/v)?
Okay, i thought so...I was confused since I'm using N with the units in a formula but I can't seem to find a way to cancel it out. Maybe you would know how? Formula: Z= Zwall x Area 4.18x10^14 mol s^-1 / 6.04x10^23 m^-2 s^-1 = Area 8.4x10^-6 m mol = r How would I elimi...
If I was trying to find out the number of molecules(N) using moles x avogadro's number, what units would N have?
A tubular fluorescent lamp in a fully evacuated supply compartment on the international space station was originally filled with a small amount of mercury vapour. When the lamp began to flicker the astronauts complained there was a tiny hole in the tube. They measured that the...
An initial-value problem is given by the differential equation, f(x,y) = 20xy2, y(1) = 1. Use the classical fourth-order Runge-Kutta method with a step-size of h = 0.02, to obtain the approximate value of y(1.02). Give your answer to 6 decimal places.
If I'm asked for the average deviation, what is the unit I should use for the answer?
An 8.07g sample of impure Ag2O decomposes into solid silver and O2(g). If 395mL O2 is collected over water at 25C and 749.2mmHg barometric pressure, then what is the percent by mass of AgO2 in the sample? The vapor pressure of water at 25C is 23.8mmHg. Could someone help me st...
