When calculating the density of liquid you measure 8.2ml in a gratuated cylinder with marking every 1 ml and measure the mass in balance 9.458g. what is the of this liquid with significant figures? consider the density calculating . if you wanted to have a more pracise density measurement typically that means spending money on better equipment . would you spend money to (a),imrove the volume measurment to 0.01ml or (b) improve the mass measurment to a 0.0001g or (c)imrove both the volume and mass measurment ? brifly explain
