Assume you measured the mass of the cart to be (500 ยฑ 1) g and the mass of the additional mass you put on the cart to be (500 ยฑ 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass

Nacidified solution was electrolyzed using copper electrodes. a constant current of 1.18 a caused the anode to lose 0.584 g after 1.52 โ 103 s. given that the charge of an electron is 1.6022 โ 10โ19 c, calculate avogadro's number. assume that copper is oxidized to cu2+ ions.
