This mapping is a critical function in the Internet protocol suite. ARP was defined in 1982 by RFC 826, which is Internet Standard STD 37. arping -i eth2 02:68:b3:29:da:98 Sends out an IPv4 ping to the IP address 255.255.255.255 with the target MAC of 02:68:b3:29:da:98. It is common nowadays to disable responding to broadcast pings. Otherwise, if you use ping, at layer 3 you won't have access to the MAC address of the ping response. However you can use pcap to sniff the network, read the ping reply with the apporpriate pcap filter, and obtain the MAC address from the arriving Ethernet frame. You can also use packet sockets to get layer 2 frames.

If you don't understand, don't worry. You won't need it. Please note that even a ping to an IP address performed from an ASA box will first cause the ASA to look up the appropriate MAC address in the ARP table (either using the IP address itself if it is on a directly connected network, or using the IP address of an appropriate next-hop), and if that is not found, the ASA will query for it itself. 1. In order for arping to be able to send an ICMP echo request (what it does when pinging MAC addresses) it needs to put in a source address in that IP packet.
