You need to know 2 things - what is the weight of the copper bar, and what are the dates on the pennies?

The reason you need to know the dates is that pennies have very different amounts of copper in them depending on when they were made. Lincoln cents from 1909 till 1942, and from 1944 to the middle of 1982 were made of 95% copper and weighed 3.11 grams, so each one has 2.955 gm of copper in it. But pennies made from the middle of 1982 to the present are mostly zinc - they weigh 2.5 gm and are 2.5% copper, so the only contain 0.0625 gm of copper apiece.

That means if you have modern (1983 and later) pennies, you'd need A LOT of them. Say the bar weighs 500 gm. You'd need 500 / 0.0625 = 8000 pennies ... plus you'd have to melt them down and separate the zinc from the copper first!
